Next generation processes have made Linear Alkylbenzene (LAB) production extremely profitable and Linear Alkylbenzene Sulfonate (LAS) the most widely used surfactant in biodegradable household detergents. LAB is produced via the alkylation of benzene with normal olefins derived from a variety of sources such as kerosene (normal paraffins) or ethylene. UOP is the global technology leader, with over 80 percent of the world’s LAB produced using our technologies. Our breakthrough catalysts and adsorbents help you achieve your desired production and product quality objectives.

With each process step in LAB complexes, UOP technology maximizes yields and lowers your operating costs. And with our committed R&D pipeline, you can be assured that you’ll have the highest product quality and newest technologies when you choose UOP.

The UOP/CEPSA Detal™ process has been the alkylation technology of choice for LAB production, accounting for 75% of all added LAB capacity since 1995. And now our latest technology, the UOP/CEPSA Detal-Plus™ process, is helping producers to meet growing demand with several distinct advantages:

  • Utilizes transalkylation of heavy alkylbenzene to produce up to 5% more LAB
  • Lowers capital investment and operating costs for new LAB complexes
  • Minimal capital investment for Detal unit revamps
  • No additional n-paraffin requirements

Minimal loss of feedstock to byproducts make the UOP Pacol™ process the most economical paraffin dehydrogenation technology available. During this process, normal paraffins are dehydrogenated to their corresponding mono-olefins using UOP’s highly active and selective DeH series of catalysts. The dehydrogenation is achieved under mild operating conditions. The Pacol process was first commercialized in the 1960’s and more than 40 units have been licensed.

The addition of a UOP DeFine™ process unit after the Pacol unit in your LAB complex results in a 5% yield increase by reducing heavy alkylate and regenerator bottoms byproducts. The DeFine process accomplishes this by selectively hydrogenating diolefins produced in the Pacol process into the corresponding mono-olefin. The DeFine process was first commercialized in the 1980’s and more than 35 units have been licensed.

The UOP PEP™ process enables the selective removal of aromatics in the olefin/paraffin feed to the Detal unit. Removal of the aromatics results in a 3-5 % increase in LAB yield and improved stability of the Detal alkylation catalyst. The PEP process was first commercialized in 1995 and more than 10 units have been licensed.

UOP provides a single source of technology supply which simplifies project execution and optimizes unit integration with an upstream n-Paraffins complex.  UOP LAB technologies provide a proven and reliable route to produce LAB in the most cost effective manner available today.
